0publish-gui is a GTK tool for publishing software through Zero Install.

By publishing an XML feed for your software on your web-site, you make it easy for people to download your programs and their dependencies, and automatically get notified of any updates you make.

0publish-gui is a GTK-based tool for creating these feeds. It allows you to describe your application, list available versions and download locations, and specify dependencies on other libraries. It also handles adding a GPG signature to the feed, so that people can check that updates really are from you.
